Thanks All, the bike is now functioning properly and i have had a four hour run today with no issues. The drive is a little quieter what with it being a sine drive and I cannot detect the controller heating up. Thanks again everyone.

Thanks saneagle. Throttle now functions as expected and I get rotation of the rear wheel. Now looking at the feed to the PAS. I assumed it would be a reed switch but i am measuring 5 volts wrt to the other two pins and also slightly negative. What is the device please? I had no idea that...

Will I break it if I get the wires round the wrong way?

Having got busy with the multimeter, am I correct that I am looking at a Hall Effect sensor?

Yes it is much appreciated saneagle. I have received a new controller to replace the one that is failing and as you warned me, the wire colour, connections etc may be wrong. So I decided to start testing with the throttle and ignore the pas initially. So I have a choice of the old throttle or...

I shall keep my fingers crossed that I don't have to do it.

Thanks again. If I need a speed sensor, would this be a reed relay and magnet on the wheel, or does it need to be synchronized? As to the combinations, what fun!

I checked carefully and you are correct! I was using my somewhat unreliable memory. From the motor connector I have three thicker wires, green, yellow and blue. Also six thinner wires, red, yellow green, blue, black and white. All the wires connect into the controller except the white wire...

Hi All. The controller (KT) has arrived and I have started fitting. The plug to the motor was too stiff to fit onto the old motor plug. So I decided to remove the new 9 pin connector and fit the old one to the connector. But i found that the 9 pin connector has 9 wires. Not very surprising i...

Thanks saneagle. Can you recommend? The bike is 2002 so I have a legal throttle ( I carry a copy of the legislation). Also brake sensors.

Hi Mechaniker. I will try looking into that. Harrys. I use 37 Volt batteries and about 1.4KWattHours. I haven't measured the capacity of the two batteries (coupled together via two big Schottky diodes) recently so they will be a bit less than that now. I can keep up with my group OK, but...

So is there a controller that has a better algorithm than my old S-KU65 please?

Concerning Harrys last comment. I went back and checked and i was mistaken. I have three large pins. I claim old age and poor eye sight! It seems to me that torque sensing, if it functions lineally, would work best with a motor at the crank. I have a rear motor and so every time i change...

I currently have an S-KU65 controller and an 810 control panel. This is cadence control. There are two drivers for a change. First, the controller probably needs changing since the drive produces a strange noise when it gets hot. I have reduced this effect by improving the thermal path to...

Hi All. I am considering modifying my old cadence sensing ebike to torque sensing. I see that Woosh have a kit to do this, but I am concerned that my Bafang motor may be too old (2002) to be compatible. The connector is a nine pin, with seven small pins and two large. Woosh tell me that...
